428 BOTANICAL GAZETTE [JUNE 
SALIX LUTEA ligulifolia, n. var.—S. cordata, in part, as inter- 
preted by Bess, Willows of California, 85, 1879, and BEBB in 
Courter, Man. Bot. Rocky Mt. Reg. p. 335. 1885.—S. cordata 
Watsoni, in part, as interpreted by BALL, in COULTER and NELSON, 
New Man. Rocky Mt. Bot. p. 132. 1909. 
When first studied this willow was regarded as a species intermediate 
between S. cordata and S. lutea, and a detailed description was written. 
Later it was considered more properly placed as a variety of S. /utea, but the 
complete description has been allowed to stand. It is hoped that fuller field 
study may be given to this interesting form.
